As a science buff and big fan of thermodynamics, I got a kick out of this article. I once wrote a short Sci-Fi story about "Entropy Engines" that sucked in air, extracted heat from the air to create power, and blows out ice-cold air. Heat is considered a waste energy, and anytime you can turn waste into a resource, you've made the world a better place.. Just don't cause another ice age.

"We are converting waste heat to electricity in an efficient, simple way by using sound," says Orest Symko, a University of Utah physics professor who leads the effort. "It is a new source of renewable energy from waste heat."
Five of Symko's doctoral students recently devised methods to improve the efficiency of acoustic heat-engine devices to turn heat into electricity. They will present their findings on Friday, June 8 during the annual meeting of the Acoustical Society of America at the Hilton Salt Lake City Center hotel."

- University of Utah physicist Orest Symko demonstrates how heat can be converted into sound by using a blowtorch to heat a metallic screen inside a plastic tube, which then produces a loud tone, similar to when air is blown into a flute. Symko and his students are developing much smaller devices that not only convert heat to sound, but then use the sound to generate electricity. The devices may be used to cool electronics, harness solar energy in a new way, and conserve energy by changing waste heat into electric power.

- Wow, heat to sound to electricity. This could be revolutionary to the field of computers and solar panels! I wonder what the efficiency rate is.
